two valves - one zone?

(1/1)

ihstiv:
I suspect that the signal would be too deprecated to operate more than one valve spliced into a single zone with the ER8 controller - can you confirm?

I'm just considering my options for when I need more than 8 valves.

The only other option is to purchase a second controller correct?

Thanks.

Hi ihstiv,

The main limitation with running two valves from one zone is water pressure.  If you have enough water pressure, and if you have a standard irrigation transformer, both solenoids should lift without a problem.  If you were going to do this you'd want to monitor the valves and the water output to make sure the valves were opening and closing and that you had sufficient water pressure.  Controlling two low flow drip zones would work with good probability of success.  If turning on two rotor zones though you'd definitely want to check your water pressure, and you'd want to monitor water hammer upon turn off - depending on flow, it's a lot of water to stop at once.

ihstiv:
Great news - thanks Jim.

I have three different water sources on my property so this may be a good option if I run out of zones.

I'll try it out when the time comes and report back on how it goes.
